Pneumatic toy gun

ABSTRACT

A pneumatic toy gun includes a first passage has a movable tube for pushing a bullet therein, and a second passage. An air path is defined between the two passages. The second passage is separated by a separating member into two partitions and one of the partitions is connected with an air hose and the other partition has an movable impact member which is connected to the tube. A spring is biased to the impact member. The separating member has an aperture communicating with the air path. The air pressure assists the tube to be pulled back after each shooting so that the toy gun can be fired continuously without pulling the cocking piece on the impact member after each shooting.

FIELD OF THE INVENTION

[0001] The present invention relates to a pneumatic toy gun which employs air pressure to pull an impact piece backward and the impact piece is biased by a spring so that the bullets are ejected by the force of the spring.

BACKGROUND OF THE INVENTION

[0002] A conventional toy gun employing air pressure for shooting bullets such as paint balls or BB bullets is powerful and could hurt the users. This is because the force that ejects the bullets is the high air pressure which has a powerful force so that the bullets are ejected out from the barrel of the toy gun at a tremendous speed. Some toy guns employ spring to eject the bullets. However, if the spring force is too strong, the user could not easily to compress it and the bullets will be ejected at a high speed which could hurt people. On the contrary, if the spring force is small, no efficient force is obtained to shoot the bullets.

SUMMARY OF THE INVENTION

[0003] In accordance with one aspect of the present invention, there is provided a pneumatic toy gun that uses pneumatic force to assist the movement of the tube after each shooting so that the trigger can be pulled continuously.

[0004] The other object of the present invention is to provide a pneumatic toy gun wherein the bullets are ejected by spring force rather than the pneumatic force.

[0005] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] Referring to FIGS. 1 to 4, the pneumatic toy gun of the present invention comprises a body 2 having a first passage 21 and a second passage 22 respectively defined therein. A barrel 210 is threadedly connected to the first passage 21 at a front end of the body 2. An air path 24 in a middle of the body 2 is defined between the first passage 21 and the second passage 22. An opening 23 is defined between the first passage 21 and the second passage 22 at a rear end of the body 2. A slot 221 is defined through the body 2 and communicates with the second passage 22. A bullet feeding hole 20 is defined through the body 2 and communicating with the first passage 21 for inserting bullets 5 therethrough.

[0013] A tube 30 having two close ends is movably received in the first passage 21. A first end piece 32 seals the first passage 21 at the rear end of the body 2. An aperture 301 is defined through a wall of the tube 30 and communicates with the air path 24 when the tube 30 is not pulled toward the first end piece 32. The tube 30 has a through hole 302 in which a connection bar 31 extends. The connection bar 31 is fixed to the tube 30 by a screw extending in a threaded hole 303 in the close end of the tube 30 and securely engaged with a groove 310 in the connection bar 31.

[0014] A front end piece 44 seals the second passage 22 at the front end of the body 2. A separating member 40 is fixedly received in the second passage 22 by a bolt 403 extending through the body 2 and fixedly connected to the separating member 40. The second passage 22 is separated in to two partitions. A third passage 402 is defined longitudinally through the separating member 40 and a radial hole 400 is defined through a wall of the separating member 40. The radial hole 400 communicates with the third passage 402 and the air path 24. A pin 41 movably extends through the third passage 402 and a first spring 43 biased between a disk 42 mounted on the pin 41 and a recess 440 in the front end piece 44 in the first partition. An impact member 33 is movably received in the second partition of the second passage 22 and the connecting bar 31 extending from the tube 30 is connected with a hole 331 in the impact member 33 via the opening 23. A recess 335 is defined in an outside of the impact member 33 so as to be engaged with a tongue 100 of a trigger 10 in the second passage 22. The pin 41 has a circular section 410 and a flat section 411, when the circular section 410 is engaged with the third passage 402, it seals the third passage 402.

[0015] A second spring 34 is biased between the impact member 33 and a second end piece 37 which seals the second passage 22 at the rear end of the body 2. A position rod 36 has a cushion ring 35 mounted thereto and is connected to the second end piece 37. A cocking piece 333 is fixedly engaged with a threaded hole 332 in the impact member 33 and extends through the slot 221.

[0016] An air hose 11 is connected to the body 2 and communicates with the first partition between the front end piece 44 and the separating member 40 in the second passage 22. A fitting 12 connected to the hose 11 is connected to an end of the handle 1 of the toy gun.

[0017] Referring to FIGS. 5 and 6, when pulling the cocking piece 333, the impact member 33 and the tube 30 are pulled back. the impact member 33 is held by the tongue 100 of the trigger 10. The aperture 301 is moved and does not communicate with the air path 24. The pin 41 is pushed by the air pressure coming from the hose 11 to seal the third passage 402. When pulling the trigger 10, the impact member 33 is pushed by the spring 34 and the tube 30 is also moved to eject a bullet 5 out from the barrel 210. The flat section 410 of the pin 41 is pushed by a protrusion 334 on the impact member 33 and the circular section 410 is removed from the third passage 402 so that air enters the third passage 402 and enters the interior 300 of the tube 30 via the air path 24 and the aperture 301. The pressure moves the tube 30 back again and the impact member 33 is also moved back for next triggering.

[0018] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
